HINGE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed August 13, 1917. Serial No. 185,804.

T 0 all whom it may concern: a

Be it known that I, JOHN J. NEWMAN, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

My invention pertains to hinges, and is more specially adapted for use in hoods of automobiles, and in similar structures where a hinge of unusual length is required. In the recent increase in the number of cylinders which are used in a motor vehicle it has been found necessary to lengthen the hood inclosing the engine to a considerable extent, with the resulting danger of the central part of the hood sagging or warp- My device not only aims to provide a hinge structure formed integrally with the metal plates of the hood, but at the same time produces reinforcin ribs extending longitudinally of the hood, at the weakest part thereof.

In the drawings :Figure 1 is a plan view of a hood of an automobile, provided with my invention. Fig. 2 is an endview of the joint thereof. Fig. 3 is a similar view, with one of the plates of the hood elevated. Fig. 4 is an outer face view of the plate 6 and accompanying knuckles 5. Fig. 5 isan end view of a modified form of my invention.

1 and 2 represent the adjoining top plates of the hood of an automobile, the inner e e of the plate 1 being turned downwardly at an angle therewith to form a plate 3, which is reflexed at its lower edge to form a strip 4, upon which knuckles 5 are struck outwardly, such knuckles ending in a strip 6, uniting all of said knuckles and tightly held between the plates 3 and 4. By forming the parts 3, 4 and 6 from a sheet of metal of sufficient strength and tenacity, and pressing such parts tightly together, no fastening means therefor is required, and a rigid support for the knuckles 5 is provided. At the same time a continuous rib of the thickness of the three plates is formed, extending the entire length of the hood.

The plate 2 is similarly formed at its edge into a downwardly projected plate 7, up-

clamped between the plates 7 and 8. The knuckles 5 and 9 alternate and are united by a pintle 11, thus forming a continuous sleeve, which is practically water-tight. The hinge thus formed permits one or other of the plates 1 and 2 to be turned upwardly at an angle with the other plate, as shown in Fig. 3.

It will be apparent that when the parts of the hinge are joined a double rib is formed just below the same, such ribs being spaced apart and extending the full length of the hood. The joint of the hinge is thus strongly reinforced, preventing any bending or sagging of the material at or near the joint.

In Fig. 5 is shown a form of my device wherein the bend between the plates 3 and 1 is omitted, and said plates and the plate 6 rigidly united by rivets 12.

My invention is preferably constructed sothat the sleeve formed by the knuckles 5 and 9 will be flush with or a little below the plane of the plates 1 and 2. This not only adds to the appearance of the hood, but when one of said plates is raised into a vertical position, as shown in Fig. 3, the angle of the movable plate comes in contact with the bend in the stationary plate, forming a stop and rest therefor, supporting said plate in its raised position.

What- I claim as my invention, and desire to secure by Letters Patent of the United States, is:

A device of the class described, comprising a pair of horizontal plates; downwardly projected spaced-apart loops formed on adjacent edges of said plates; alternating knuckles formed on the loop extensions and disposed beneath the plane of said hori zontal plates; and reinforcing plates projected from said knuckles into the spaces in said loops, the angles formed between said plates and their respective loops coacting as stops, to hold either of said plates in a perpendicular position with relation to the other one thereof.

In testimony whereof I afiix my signature in the presence of two witnesses.

JOHN J. NEWMAN.
